Title: Embedded transmission line coupler for radio frequency signal amplifiers
Inventor: KLOMSDORF ARMIN
IPC: H01P5/18
Filed: 1994-10-06
Abstract: A transmission line coupler (115) for a transmitter output signal (123) generated by an RF signal amplifier (103) includes a through-path transmission line (201) and a coupled-path transmission line (202) electromagnetically coupled thereto by multiple serpentine-like portions (such as portions 641, 642, 643 and 644 in Fig. 6), which are disposed on opposite sides of the through-path transmission line (201) for enhancing coupling sensitivity and eliminating degradation in the amount of coupling due to variations in the transmission line plating registration. Offset portions (641, 643) on one side of the through-path transmission line (201) provide substantially the same amount of coupling as the offset portions (642, 643) on the other side of the through-path transmission line (201). The transmission line coupler (115) is embedded in the output match of the final amplifier (103) and includes complex impedances (212 and 210, 222) at each port of the coupled-path transmission line (202) for substantially eliminating undesired reflections. The coupled port of the coupled-path transmission line (202) is coupled by an inductor (211) to a hot-carrier diode (206) for enhancing the detection sensitivity thereof. <IMAGE>

Title: Compressor
Inventor: MCGRATH MICHAEL ALAN
IPC: F04B39/04
Filed: 1994-06-02
Abstract: An electromagnetic linear compressor has a linearly reciprocating piston (10) biassed in one direction by a helical coil spring. A rotational bearing (40) supports one end of the spring (20a, 20b). To avoid uneven wear due to forces applied by the spring, the spring is replaced by a spring system comprising two helical coil springs (20a, 20b) acting is series to bias the piston (10), and the rotational bearing (40) transmits thrust between the two springs while permitting relative rotation of the two springs about their axis. The compressor also has turbine means (30) for exerting a unidirectional rotational force to rotate the piston (10) about its axis gradually during operation of the compressor. <IMAGE>

Title: Apparatus for key distribution in an encryption system
Inventor: HAWTHORNE WILLIAM MCMULLAN
IPC: H04L9/08
Filed: 1994-09-14
Abstract: An encryption/decryption apparatus enables encrypted communication between two stations each incorporating such an apparatus. The apparatus is arranged when acting as sender to create (at 71) a mutual primitive from stored items of data, to generate a random session key and encrypt the random session key (at 73) in accordance with the mutual primitive for transmission of the encrypted session key to the recipient station. The sender apparatus further encrypts the main message (at 72) in accordance with the random session key for transmission of the encrypted message to the recipient station. The sender apparatus also stores a registration code and transmits this to the recipient station, where it is decoded (at 74) to recreate the mutual primitive from items of data stored at the recipient station. The recipient apparatus decrypts the encrypted session key (at 75), using the recreated mutual primitive, and then decrypts the main message (at 76) using the recreated random session key. <IMAGE>

Title: Telecomm alarm correlation
Inventor: ROSS NIALL
IPC: H04M3/22
Filed: 1996-10-21
Abstract: A method of processing data such as alarms from a communications network, by alarm correlation, the network comprising entities which offer and receive services to and from each other, the method comprising the step of: adapting a virtual model (87) of the network according to events in the network. The model comprises a plurality of managed units (91,92) corresponding to the network entities, each of said units containing information about the services offered and received by its corresponding entity to and from other entities, and having associated knowledge based reasoning capacity such as rules, for adapting the model by adapting said information. When one of the managed units is notified of an event such as an alarm raised by its corresponding entity, the cause of the alarm is determined using the virtual model. The development and maintenance of rules is easier, and correlation quicker since the rules for each unit need not relate to all the other units.

Patent GB-2313169-A (GB)
Title: A coupling device having torque limiting means
Inventor: CHLUDEK ADRIAN
IPC: F16H48/26
Filed: 1997-05-16
Abstract: A coupling device comprises a friction coupling 12 operated by an actuating device 13 having an annular pressure chamber 21 containing a viscous fluid pressurized by a rotational member 22 and a disc-shaped pumping/control member 23. When housing 14 and hub 16 rotate relative to one another the rotational member 22, which is frictionally fixed to hub 16, produces shear forces in the viscous fluid and a pressure rise results. This pressure rise acts on a piston 19 which loads the friction coupling 12. The rotational member 22 is attached to the hub 16 via, for example, frictional slip couplings 102, 103 or claw couplings (see fig 7c) so that as the relative speed between the hub 16 and housing 14 increases the rotational member 22 slips, thereby limiting the shear forces produced and consequently the torque transmitted by the friction coupling 12. In another embodiment a size of a shear channel 38 is increased by deforming a U-shaped resilient member (121, fig 8c), thereby limiting the pressure acting on piston 19. A further embodiment involves restricting the pressure by providing a rotational stop (201, fig 9b) which causes a short-circuiting between a channel (32, fig 9b) and a reservoir 26.

Title: Blank for forming a carton that has the shape of a book.
Inventor: HALLAM CHRISTOPHER
IPC: B65D5/20
Filed: 1998-02-06
Abstract: A blank (Fig 2) is foldable into a carton that has the shape of a hardback book 2. The base 12 is formed to look like one cover and the lid 8 looks like the other. The extending edges 22 of the base are formed by a marginal flange 34 on the base panel 12 folded back on itself to overlie the base panel and a marginal flange 36 on the side wall 38 folded to overlie the base panel marginal flange. This arrangement provides less stress and a greater gluing area at the extending edges. Preferably, the side wall marginal flange is foldably connected to the base panel marginal flange. The comer arrangement at the ends of the spine of the book is reinforced by providing a gusseting (48, 50, 52, 54, Fig 2) between the adjacent walls. The folds (56, Fig. 2) in the corner gusset are arranged so that the spine is drawn in beyond the vertical so that the bulging caused by the extra blank material required in the corner is hidden. The corners may be held together by gluing or interlocking tabs and slots.
